- Close XBMC

Log is

- Select VSX-921 at default audio device in Windows.
- Start XBMC, select Wasapi VSX-921 in audio device.
Log is

- Close XBMC
- Start XBMC, start a multichannel FLAC. Stop, exit, get the log.

And now... audio is working... No more problem VIA vs nVidia !!!
I don't understand, as i've checked twice next time...
Well... it means no issue, problem closed.
Nevertheless, the logs show interesting things : The problem of 2 channels occurs only during enumerate of devices. When asked for a specific format when file is played, the answer is positive.
I've checked more properly on my receiver, the file with DTS-HD MA audio is indeed labeled DST-HD MA on my receiver, so test Ok for it.
